GeForce GTX 650 Ti vs Radeon HD 3470 512MB

Intro

Compare all that to the Radeon HD 3470 512MB, which makes use of a 55 nm design. AMD has clocked the core speed at 800 MHz. The GDDR3 RAM works at a speed of 950 MHz on this particular card. It features 40(8x5) SPUs as well as 4 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti should in theory perform quite a bit faster than the Radeon HD 3470 512MB overall. (explain)

GeForce GTX 650 Ti		86400 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 56000 (184%)

Texel Rate

The GeForce GTX 650 Ti should be quite a bit (about 1756%) better at AF than the Radeon HD 3470 512MB. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 56192 (1756%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 650 Ti is a better choice, and very much so. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 11648 (364%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
